The Dynamic Research of Industrial Sewing Machines Based on the Modal and Operational Deformation Analysis

Abstract:

The vibration of the operational sewing machine is caused mostly by the fundamental frequency of the motor and its harmonic frequencies. The experimental modal analysis was conducted on a certain industrial sewing machine to identify its modal parameters. The operational deformation analysis was carried out and the actual deformation in the first six harmonic frequencies of the main speed frequency was obtained. Finally, the dynamic characteristic was identified by analyzing how each mode influences the harmonic vibration. This paper provides a valuable reference for noise reduction of the sewing machine.
